Sounding discussion
The 00z sounding shows a deep layer northwest flow pattern has
taken hold of the area today. This northwest flow extends from the
surface to above 500mb. What this northwest flow has done is
produce a very stable airmass in the mid and upper levels due to
warming and drying of the overall atmosphere. This is most
observable by the weak lapse rates between 850 and 500mb of only
5.8c km, low mixed layer CAPE of only 106 j kg, and increase in
freezing levels by 1200 feet to nearly 16000 feet. A good sign
that the atmosphere has experienced drying since this morning is
the significant drop in the mean mixing ratio from 17.2 g kg to
13.5 g kg this evening. Overall, the atmosphere has turned more
stable and drier since the morning sounding. 32

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
